Question

What is the common ratio of the geometric sequence below?

Answer 1

Answer:

The answer is option B

Step-by-step explanation:

Since it's a geometric sequence, to find the common ratio divide the previous term by the next term.

That's

$\frac{48}{ - 96} = - \frac{1}{2}$

And also

$\frac{ - 24}{48} = - \frac{1}{2}$

$\frac{12}{ - 24} = - \frac{ 1}{2}$

Also

$\frac{ - 6}{12} = - \frac{1}{2}$

Since the common ratio is the same for any of the terms chosen the common ratio of the sequence is

$- \frac{1}{2}$

Hope this helps you

Answer 2

Answer:

B. -1/2

Step-by-step explanation:

The common ratio is the ratio between two numbers next to each other To find the common ratio, divide a term by the preceding term.

For example, if the term is 48, divide by -96.

48/-96 = -1/2

Another example, if the term is -24, divide by 48.

-24/48= -1/2

Let’s try one more example. If the term is 12, divide by -24

12/-24= -1/2

Therefore, the common ratio is 1/2 and the correct answer is B.
